An F/2.8 high-speed zoom made for full-frame mirrorless

Packing cutting-edge technology into a compact body, Tamron has created a high-speed zoom lens specifically designed for mirrorless cameras: the 28–75mm F/2.8 Di III RXD (Model A036). A great addition to the Sony E-mount, the A036 strikes a beautiful balance between vibrant image quality, superb bokeh, compact size and lighter weight.
Specialized glass elements throughout control various aberrations and produce stable resolution across the entire zoom range. All the lens surface is treated with Tamron’s proprietary BBAR (Broad-Band Anti-Reflection) Coating, which dramatically reduces ghosting and flaring while preserving crisp image quality. The A036 also incorporates an all-new high-speed precision AF drive system with an RXD (Rapid eXtra-silent stepping Drive) motor unit that is remarkably quiet.
In addition to portraits, nature shots and street photography, the 0.19m Minimum Object Distance (MOD) lets you enjoy new forms of photographic expression with close-up shooting at the wide-angle end. With Moisture-Resistant Construction and Fluorine Coating, this lens offers exceptional mobility and outdoor functionality. It is the only zoom you need to portray the world in all its full-frame beauty.

Outstanding image quality meets delicate bokeh

Focal length:64mm Exposure:F/2.8 1/250sec ISO: 100

The A036 zoom delivers a dazzling balance of clear yet soft rendering, stunning bokeh and exceptional resolution for in-focus areas. It also captures the finer details across the entire focus plane with performance that supports the latest high-resolution cameras—all while expressing the characteristic smoothness of a fast aperture lens.
Stunning bokeh spreads gently from the plane of focus to highlight your subject. By stopping down the aperture, you can alter how images are rendered. The lens also incorporates a nine-bladed aperture that produces beautifully round defocused light points. And Tamron’s distinctive image characteristics, which produce more than just a different degree of blur with F-stop changes, add even more impact.

The A036 zoom is designed to maximize the potential of full-frame mirrorless cameras. Because it is designed to be your most frequently used high-speed zoom, we made it compact. Now you can enjoy advanced optical performance in a compact size with lightweight convenience. Weighing just 550g (19.4 oz) with a length of 117.8mm (4.6 in), the A036 lets you take advantage of the mobility offered by mirrorless cameras for everything from everyday snaps and commemorative photos to specialized photography.

The Model A036 breaks all the rules regarding MOD. No longer must the MOD of a zoom lens be fixed throughout the focal range. The A036 reaches a MOD of 0.19m (7.5 in) at the 28mm wide-angle end achieving a maximum magnification ratio of 1:2.9. A working distance of just 5.7cm (2.24 in) from the front element allows you to shoot close-up with a sense of perspective unique to wide angles. At the 75mm telephoto end, the 0.39m (15.3 in) MOD provides an image magnification of 1:4, allowing close-up shooting with a pleasantly blurred background similar to a macro lens.

Superb AF keeps it sharp and quiet

The AF drive on the A036 includes an RXD (Rapid eXtra-silent stepping Drive) motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that accurately detects the position of the lens enables high-speed and precise AF, which is ideal when shooting continually moving subjects or video. With a focusing system that is both smooth and quiet, the A036 lets you shoot a video without worrying about picking up ambient drive sounds.

The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

The A036 zoom features our new “Human Touch” design, a mixture of form and function embodied by the “Luminous Gold” brand ring above the lens mount. It tells you that no detail has been overlooked in creating a design and feel that’s easy to work with—everything you look for in a photography partner. And everything you expect from Tamron.

MTF Chart Guide

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.

The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.

Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.

Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
